Be it known that ll, SAMUEL M. GRossMAN, a citizen of the United States,residin at hicago, in the county of Cook and tate of Illinois, haveinvented new and useful Improvements in Method of Making Finger Rings,of which the following is a specification.

This invention relates to finger rings, and more particularly weddingrings, and the method of making the same.

One object ofmy invention is to make the ring of two separate annularparts, one being relatively thicker than the other and constituting thebody of the ring, and the other part being in the form of a relativelythin'ornamental band fitted tightly in an outwardly opening channel inthe rin body with the band fitting between the side anges of the channeland being substantially flush with the outer surface of the ring body onop osite sides of the channel.

nother object of the invention is to have the ornamental band fittightly in the channel Without the use of solder, this beingaccomplished by varying the diameter of the ring body and bandrelatively to each other after the band has been applied in the channel,thus holding the hand against circumferential movement with respect tothe ring body.

A further object of my invention is to cut 'out the side edges of theband to conform to the design on which the band is fashioned so that thebottom of the channel may be visible on opposite sides of the band, andthus furnish a background for the band and set off the same, especiallywhen the ring one color, say green gold, and the band is made of acontrasting color, as for instance white gold.

Uther and further objects of the invention will appear from thefollowing specification, taken in connection with the accompanyingdrawings, in whic Fig. 1 is a perspective view of a finger rin' made inaccordance with my invention;

. igs. 2 to 5 inclusive illustrate the respective steps followed inmaking the ring by the method of my invention;

Fig. 6 is an enlarged fragmentary top plan view of the ring showni'n thepreceding figures after the ring body and band have .been fittedtogether; and

Fig. 7 is an enlarged side elevational view of a ring, with a port on nsection, showing Serial No. 444,683.

an ornamental band applied in the channel 1n the side of the ring, aswell as around the outer circumference of the same. v The finger ring ofmy invention is made in two separate annular parts 1 and 2, the formerbeing relatively thicker than the latter and constituting the body ofthering. -As shown in the'drawings, the ring body 1' is provided with anoutwardly opening cha nel 3 extending completely about the outside ofthe ring body and having side flanges 4, 4, annular in form andprojecting radially outward substantially the same distance.

The other or outer part 2 of the ring is in the form of a relativelythin annular band having a width to fit in the channel 3 between theside flanges 4 thereof, and a diameter, w-hen first made, slightlygreater than that of the bottom of the channel, as shown in Fig. 3. Theouter surface of the band 2 may be chased or carved to give it anydesired ornamental and and its side edges are cut in conformity.- withthe design on which the band is fashioned.

After the parts 1 and 2 have been made separately and given annularform, as shown in Fig. 2, the band 2 is forced over one of the flanges 4until it is in the channel 3 and surrounding the ring body 1, asillustrated in Fig. 3. At this time, the band 2' is slightly namentalband 2 and cause it to fit tight in the channel 3. The full effect ofthis expansion may be gained by inserting the mandrel 5 through a holein an anvil 6 with the ring resting thereon, as shown in Fig. 5. Theupper end of the mandrel 5 is tapped with a hammer or mallet 7, shown indotted lines in said Fig. 5, to expand the ring body 1 to the extentrequired. After this has been done, the edges of the ring body-1 may befiled or otherwise finished to be made smooth, and the whole-polishedand buffed togive it a proper and desired finish and luster.

As shown in Fig. 6, portions of the band 2 extend across the channel 3and engage against the side flanges 4 thereof. This holds artisticdesign,

the band 2 against lateral displacement in the channel. The side edgesof the band between such portions, being cut out or carved to conform tothe design on which the band is fashioned, terminate short of saidflanges, and thus expose to view portions of the bottom of the channel 3on opposite sides of the band. This has a dual purpose. First, it allowsthe contour of the design of the band at its sides to be readilyobserved and be set out, and, second, the bottom of the channel beingpolished and having a luster forms a background for the ornamental bandto set it off with a pleasing and ornate eifect. 4

This eifect is further accentuated when the ring body 1 and band-2 aremade of metals having contrastin colors, as for instance the ring body 10 green gold and the band 2, of white gold. Should solder be used tosecure the parts together, the bottom of the channel would not form'abackground for the band, because the solder on fusing would run beyondthe side edges of the band and substantially, if .not wholly, fill thespaces mentioned.

In Fig. 7, I have shown an ornamental band 7 applied in an annularchannel 8 in one side of a ring body 1. These parts are fitted togetherby expanding the ring body, in the same manner as shown in the precedingfigures and as heretofore de- Applied about this ring body 1 is anornamental band 2*, the same as before. The ring shown in Fig. 7 is thusprovided with two ornamental bands, one on one side and the other aboutthe ring. A third band could be employed by fitting the same in achannel on the opposite side of the ring.

The ring of my invention is especially applicable as a wedding ring, asthe bands may be made in varied designs, now ordinarily chased onwedding rings.

While I have shown and described herein in detail a finger ring of myinvention and the method by which it is made, it is to be of courseunderstood that the details shown and described may be variously changedand modified without departing from the spirit and scope ofmy'invention.

I claim as my invention:

1. The method of making a finger ring, consisting in, first, making thering in two separate annular parts, one constituting the body of thering, and the other the ornamental band therefor, second, providing thering body with an annular channel having side flanges, third, applyingthe band in the channel between said flanges, and, fourth, causing theband to fit tight in the channel in the ring body by varying the"diameter of one with respect to the other.

2. The method of making a finger ring, consisting in, first, making thering in two separate annular parts, one constituting the body of thering and the other the ornamental band therefor, second, providing saidI ring body with an annular channel extending about the outercircumference of the same and having side flanges, tl1i1d,f01'cing saidband over one of said side flanges into said channel, and, fourth,causing the band to fit tight against the bottom of said channel byvarying the diameter of the band and ring body relatively to each other.

3. The method of making a finger ring, consisting in, first, making thering in two separate annular parts, one constituting the body of thering and the other the ornamental band therefor, second, providing saidring body with an annular channel extending about the outercircumference of the same and having side flan es, third, forcing saidband over' one of sai side flanges into said channel, and, fourth,expanding the ring body into tight contact with the band.

In testimony that I claim the foregoing as my invention, I afli'x mysignature this 8th day of Februar A. D. 1921.
